[分享]FRED如何调用Matlab [复制链接]

简介：FRED作为COM组件可以实现与Excel、VB、Matlab等调用来完成庞大的计算任务或画图，本文的目的是通过运行一个案例来实现与Matlab的相互调用，在此我们需要借助脚本来完成，此脚本为视为通用型脚本。 v(DwU!  
P$Z}  
配置：在执行调用之前，我们需要在Matlab命令行窗口输入如下命令： V0K16#}1gM  
enableservice('AutomationServer', true) JD6aiI!Su  
enableservice('AutomationServer') t, U) ~wi  
>+cSPN'i>  
结果输出为1，这种操作方式保证了当前的Matlab实体可以用于通信。 AXwaVLEBQ

在winwrp界面，为增加和使用Matlab类型的目录库，我们需要如下步骤： 3&'2aW  
1. 在FRED脚本编辑界面找到参考. [SVhtrx|%  
2. 找到Matlab Automation Server Type Library Cye T]y  
3. 将名字改为MLAPP GCDwWCxh

在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix，PutWorkspaceData适用于存储一般的数据在工作区，并赋予其为变量，PutFullMatrix试用于复数数据。 dsJm>U)

现在将脚本代码公布如下，此脚本执行如下几个步骤： qO-9 x0v#  
1. 创建Matlab服务器。 -LtK8wl^  
2. 移动探测面对于前一聚焦面的位置。 C5xag#Z1  
3. 在探测面追迹光线 (n,u|}
8Y  
4. 在探测面计算照度 <aJ$lseG  
5. 使用PutWorkspaceData发送照度数据到Matlab _;56^1'T  
6. 使用PutFullMatrix发送标量场数据到Matlab中 r-}-C!  
7. 用Matlab画出照度数据 >M]6uf  
8. 在Matlab计算照度平均值 E<>*(x/\e  
9. 返回数据到FRED中 S,)d(g3>
